Nathan Froyd 01583602a9 Bug 1207245 - part 6 - rename nsRefPtr<T> to RefPtr<T>; r=ehsan; a=Tomcat
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout.  The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

CLOSED TREE makes big refactorings like this a piece of cake.

 # The main substitution.
find . -name '*.cpp' -o -name '*.cc' -o -name '*.h' -o -name '*.mm' -o -name '*.idl'| \
    xargs perl -p -i -e '
 s/nsRefPtr\.h/RefPtr\.h/g; # handle includes
 s/nsRefPtr ?</RefPtr</g;   # handle declarations and variables
'

 # Handle a special friend declaration in gfx/layers/AtomicRefCountedWithFinalize.h.
perl -p -i -e 's/::nsRefPtr;/::RefPtr;/' gfx/layers/AtomicRefCountedWithFinalize.h

 # Handle nsRefPtr.h itself, a couple places that define constructors
 # from nsRefPtr, and code generators specially.  We do this here, rather
 # than indiscriminantly s/nsRefPtr/RefPtr/, because that would rename
 # things like nsRefPtrHashtable.
perl -p -i -e 's/nsRefPtr/RefPtr/g' \
     mfbt/nsRefPtr.h \
     xpcom/glue/nsCOMPtr.h \
     xpcom/base/OwningNonNull.h \
     ipc/ipdl/ipdl/lower.py \
     ipc/ipdl/ipdl/builtin.py \
     dom/bindings/Codegen.py \
     python/lldbutils/lldbutils/utils.py

 # In our indiscriminate substitution above, we renamed
 # nsRefPtrGetterAddRefs, the class behind getter_AddRefs.  Fix that up.
find . -name '*.cpp' -o -name '*.h' -o -name '*.idl' | \
    xargs perl -p -i -e 's/nsRefPtrGetterAddRefs/RefPtrGetterAddRefs/g'

if [ -d .git ]; then
    git mv mfbt/nsRefPtr.h mfbt/RefPtr.h
else
    hg mv mfbt/nsRefPtr.h mfbt/RefPtr.h
fi

--HG--
rename : mfbt/nsRefPtr.h => mfbt/RefPtr.h
